### Run e2e tests with another database

It is still documented for the sake of completeness:
You can also perform e2e tests using MariaDB/MySQL or PostgreSQL if you want.

Although the main goal of e2e is assertion testing, we have added a framework for visual regress testing. If you are working on front-end features, please use the following:
- Check out `main`, `make clean frontend`, and run e2e tests with `VISUAL_TEST=1` to generate outputs. This will initially fail, as no screenshots exist. You can run the e2e tests again to assert it passes.
- Check out your branch, `make clean frontend`, and run e2e tests with `VISUAL_TEST=1`. You should be able to assert you front-end changes don't break any other tests unintentionally.

VISUAL_TEST=1 will create screenshots in tests/e2e/test-snapshots. The test will fail the first time this is enabled (until we get visual test image persistence figured out), because it will be testing against an empty screenshot folder.
